The Christian is to proclaim and prosecute

The Christian is to proclaim and prosecute an irreconcilable war against his bosom sins; those sins which have lain nearest his heart, must now be trampled under his feet. So David, ‘I have kept myself from my iniquity.’ Now what courage and resolution does this require? You think Abraham was tried to purpose, when called to take his ‘son, his son Isaac, his only son whom he loved,’ Gen. 22:2, and offer him up with his own hands, and no other; yet what was that to this? Soul, take thy lust, thy only lust, which is the child of thy dearest love, thy Isaac, the sin which has caused the most joy and laughter, from which thou hast promised thyself the greatest return of pleasure or profit; as ever thou lookest to see my face with comfort, lay hands on it and offer it up: pour out the blood of it before me; run the sacrificing knife of mortification into the very heart of it; and this freely, joyfully, for it is no pleasing sacrifice that is offered with a countenance cast down —and all this now, before thou hast one embrace more from it. Truly this is a hard chapter, flesh and blood cannot bear this saying; our lust will not lie so patiently on the altar, as Isaac, or as a ‘Lamb that is brought to the slaughter which was dumb,’ but will roar and shriek; yea, even shake and rend the heart with its hideous outcries.
